Who We Are
One Tech.
Every Code.
KISS Diagnostics isn’t a software company or a content farm. It’s one licensed technician putting 20 plus years of real diagnostic work into something the whole trade can use.
The Story
Born from late nights and stubborn codes

KISS Diagnostics started the way most useful things in this trade do — out of necessity, not a business plan. It came from late-night personal research on difficult diagnostic cases, the kind of digging every serious tech does when a vehicle won’t give up its answer easily.

After years of building that knowledge one stubborn code at a time, the idea was simple: turn it into something clean, fast, and usable for any tech standing in front of the same problem — not a 400-page manual, not a forum thread with fifteen conflicting answers. One sheet. One code. What actually matters.

That’s the whole philosophy. Keep It Simple, Smart.

Background
  • Licensed 310S Automotive Service Technician
  • 20 plus years of professional experience across dealerships and independent shops — both hourly and flat rate
  • Specializes in general repair and driveability diagnostics — powertrain, drivetrain, and custom exhaust
  • Additional experience in material handling and heavy equipment
  • Consistently the shop’s lead driveability technician — the one other techs turned to when a vehicle wouldn’t give up its answer
Why It’s Different
Written by the tech who’s been the last stop

When a vehicle stumped everyone else in the shop, it landed on this bench. That’s not a résumé line — it’s where these sheets actually come from. Every cause ranked, every flowchart step, every pro tip is built from real cars that didn’t fit the textbook the first time around.

The Name
Keep It Simple, Smart

Not "keep it simple, stupid." Diagnostics isn’t stupid work — it’s some of the most demanding problem-solving in any trade. The "smart" is the point: strip away everything that doesn’t help you find the fault, and hand over exactly what a sharp tech needs to move fast.

KISS
Keep It — no fluff, no filler, no 40-page PDFs. Just the diagnostic path for one code, start to finish.
Simple — one sheet per code, plain language. Open it on a phone in the bay and know exactly what to check first.
Smart — built from 20 plus years of real fault patterns, not a database dump, but how an experienced tech actually thinks through a code.
